What is the range of the function y=3 square root x+8

Mathematics
1 answer:
klasskru [66]4 years ago
4 0

Answer with explanation:

⇒Range of function in two variables ,that contains variables x,and y are those values of y, for which x is defined.

For example ,consider the linear function , y=x

the set of values that ,x can take for which y is defined called Domain of the function.x∈R

And, the set of values that ,y can take for which x is defined called Range of the function.y∈R

The given function is

y=(x+8)^{\frac{1}{3}}

Taking cube on both sides

y^3=x+8\\\\x=y^3-8

→x is defined for all real values of y ,means for all real values of y,we are getting real values of x.So Range of the given function is ,y∈R.

Option A:→ -∞≤y≤∞

Item 19 You pay $40 each month for satellite TV, plus $3.50 for every movie you purchase. Write and solve an equation to find th
Marianna [84]
Let x be the number of movies purchased. If each movie you purchase costs $3.50 dollars, this means that the total cost of x movies in one month is $3.50x
In addition, you have to pay $40 for satellite TV. We can now find an equation to find the total cost per month:
40 + 3.50x

Now, by hypothesis, you paid $57.50 during a month as a total bill.
Which means that 40 + 3.50x = 57.50
We need to find the number of movies purchased during that month, or, in mathematical words, we need to solve for x.

40 + 3.50x = 57.50

First, let's put the variables apart and the numbers apart by subtraction 40 from each side, so we get:
40 - 40 + 3.50x = 57.50 - 40
3.50x = 17.50

Now divide both sides by 3.50
(3.50x)/(3.50) = 17.50 / 3.50
x = 5

So, during that month, you purchased 5 movies.

Hope this helps! :)

5. What property of equality is used to transform the equation from the first step to the second step?
Novay_Z [31]

Answer: The multiplication property of equality is used to transform the equation from the first step to the second step.

Explanation:

The multiplication property states that if any number is multiplied both side of a equation the equation doesn't change.

If x = y and we multiply both side by m, then xm = ym is equivalent to x = y.

The given expression is,

\frac{x}{5}=2

Use multiplication property of equality, multiply 5 both sides,

x=2\times5

x=10

Therefore, the multiplication property of equality is used to transform the equation from the first step to the second step.

HELP HURRY WILL GIVE BRAINLIEST
rusak2 [61]

Answer:

That's all you're doing is writing the equation for two lines and finding out where they intersect. The slope is how much the price is increasing or decreasing and the y-intercept is where the price is starting at.

x = number of hours

y = mx + b = 0.12(x + 3) + 15.21     {It's (x + 3) because we have to add the 3 hours between 9 and noon}

y = mx + b = -0.11x + 15.96       {The slope is negative because the price is decreasing}

Set them equal to each other

0.12(x+3) + 15.21 = -0.11x + 15.96

Now solve for x

0.12x + 0.36 + 15.21 = -0.11x + 15.96

0.12x + 15.57 = -0.11x + 15.96

0.12x + 0.11x = 15.96 - 15.57

0.23x = 0.39

x = 0.38 / 0.23 = 1.7 hours

Convert 0.7 into minutes

0.7 hours * (60 min / 1 hour) = 42 min

So the prices are the same 1 hour and 42 min after noon, which is 1:42 PM

Write the equation a line that has a slope of -4 and goes through point (1,-5)
GuDViN [60]

The equation a line that has a slope of -4 and goes through point (1,-5) in slope intercept form is y = -4x - 1

<h3><u>Solution:</u></h3>

Given that line that has a slope of -4 and goes through point (1,-5)

We have to write the equation of line

<em><u>The slope intercept form is given as:</u></em>

y = mx + c ------- eqn 1

where "m" is the slope of line and "c" is the y - intercept

Substitute slope "m" = -4 and (x, y) = (1, -5) in eqn 1

-5 = -4(1) + c

-5 = -4 + c

c = -5 + 4 = -1

<h3>c = -1</h3>

<em><u>Substitute c = -1 and m = -4 in eqn 1</u></em>

y = -4x - 1

Thus the required equation of line is found
